One gram of fat contains 9 calories. This value is consistent across multiple authoritative sources and is used as a standard measure in nutrition to calculate energy intake from fats
. To summarize:
- Fat provides 9 calories per gram.
- This is higher than carbohydrates and protein, which provide about 4 calories per gram each.
- The 9 calories per gram figure is an average and widely accepted for dietary calculations.
Therefore, when calculating calories from fat, you multiply the grams of fat by 9 to get the total calories from fat. For example, 50 grams of fat would provide 450 calories (50 x 9 = 450)
